Description Dhananjay Arunesh 2019-02-26 12:55:55 UTC
An issue was discovered in Exiv2 0.27. There is infinite recursion at BigTiffImage::printIFD in the file bigtiffimage.cpp. This can be triggered by a crafted file. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact.


Comment 1 Dhananjay Arunesh 2019-02-26 12:56:06 UTC
Created exiv2 tracking bugs for this issue:

Affects: fedora-all [bug 1683202]

Comment 2 Stefan Cornelius 2019-03-07 13:17:43 UTC

This issue did not affect the versions of Exiv2 as shipped with Red Hat Enterprise Linux 6 and 7 as they did not include support for BigTIFF images.
